Compatibility
-------------
The yaml package supports most of YAML 1.1 and 1.2, including support for
The yaml package supports most of YAML 1.2, but preserves some behavior
from 1.1 for backwards compatibility.
Specifically, as of v3 of the yaml package:
- YAML 1.1 bools (_yes/no, on/off_) are supported as long as they are being
decoded into a typed bool value. Otherwise they behave as a string. Booleans
in YAML 1.2 are _true/false_ only.
- Octals encode and decode as _0777_ per YAML 1.1, rather than _0o777_

actually never supported by this package as it's clearly a poor choice.

// have its original textual representation preserved. An effort is made to

// describe, though.

// var person struct {
